Gwen Stefani

Stefani attributes her cutting-edge style to her split personality. "I'm a geeky Orange County girl, a chola girl, a rasta girl and an English girl-all mixed together." The now expectant star showed off her gams in an inspired jumper from her L.A.M.B. line.

Rihanna

Rihanna rocked the Kids' Choice Awards in an H&M bustier paired with tapered Stella McCartney trousers. "I like high-fashion looks, but I never take it too far," Rihanna has said. "I always bring it back to who I really am." Since chopping her hair into an angled bob, Rihanna has favored primary-colored leather jackets (with matching nail polish), latex leggings and towering platforms.

Sarah Jessica Parker

Like Carrie, her famous Sex and the City character, Sarah Jessica Parker isn't afraid to take fashion risks. Along with basics from her Steve & Barry's line, Bitten, Parker favors sky-high heels, statement jewelry and curve-hugging dresses, like this sparkling number from L'Wren Scott.

Rachel Bilson

Jumper lead Rachel Bilson has become a fashion favorite with her mix-and-match ensembles. "I like to add my own thing to an outfit," she has said. "Like, if I'm wearing a fancy dress, I'll put a beanie on." For a visit to Rome, she tossed a Burberry leather jacket over skinny jeans and accessorized with a Matthew Williamson scarf and Christian Louboutin studded boots.

The actress loves her quirky-chic style combos-like adding an embroidered headband to a sequined See by Chloe dress. What else sets her apart from the Hollywood crowd? "I never wear high heels because I feel ridiculously tall," the 5'9" star has told In Style.
